A writing aid that turns a list of software changes into release notes using the Keep a Changelog format, a commonly used structure for documenting versions.

In plain words
What is it for?
Use it when preparing release notes from commits or other raw change descriptions.
Why use it?
It replaces cryptic commit wording and a messy change list with clear notes grouped by what was added, changed, fixed, removed, deprecated, or related to security.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

changelog scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 11d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

Changelog

Turn the user's raw list of commits/changes into clean release notes in the Keep a Changelog style.

Format:

## [<version>] - <YYYY-MM-DD>

### Added
- …
### Changed
- …
### Fixed
- …
### Removed
- …
### Deprecated
- …
### Security
- …

Rules:

  • Group each change under the right heading; omit headings with no entries.
  • Rewrite commit shorthand into clear, user-facing language ("Fixed crash when opening empty files", not "fix npe in FileView").
  • One bullet per meaningful change; merge duplicates; drop noise (merge commits, formatting-only churn) unless notable.
  • Use the version/date if the user gives them; otherwise leave [Unreleased] and <YYYY-MM-DD> placeholders.
  • Lead with what matters most to users. Output only the changelog.
Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
